Multifunctional 3D MXene@MDCF Nanoarchitectures via Hierarchical Networks Self‐Assembled Strategy Achieving Superior Electromagnetic Wave Absorption and Flame Retardancy with Enhanced Thermal Management

(213.5% higher than pure EP), enabling efficient heat dissipation. Furthermore, the composite exhibits superior flame retardancy, reducing peak heat release rate and total heat release by 25.7% and 30.46%, respectively, through the formation of dense carbon layers. This work provides a cost-effective strategy for multifunctional electronic packaging materials with integrated wave-absorption, thermal management, and flame-retardant properties.
